Worldwide Service

Ralph Mueller and Associates is located in Arizona, but that doesn’t stop us from providing service to clients all over the world. We offer free quotes to anyone interested in selling and also have an on-site gemological lab that allows us to better inspect gold and gemstones. We also provide strict confidentiality to all of our clients. 

The Importance of GIA-Certification

The Gemological Institute of America is the world leader in gemological research and studies in the world. They are the brilliant minds behind the 4Cs of diamond grading and have helped jewelers everywhere better understand diamonds and gemstones so that they may provide their clients with better and more knowledgable service. 

The GIA-certification process is incredibly in-depth. It breaks down the 4Cs and teaches jewelers how to understand the correlation between a diamond’s weight and size. They also learn about the world’s most popular colored gemstones, as well as jewelry design and style. 

The GIA is also incredibly passionate about protecting the consumer. They make sure to teach jewelers about the process of selling and marketing jewelry. After completing their certification, jewelers are able to explain the differences between imitation, lab-grown, and treated gems, easily to their clients to help them better understand what they’re buying.
